Al Jazeera does a documentary series called Fault Lines, which is about struggles going on in the world. The documentaries are amazing, and everyone should watch them. Most of them are pretty depressing because the world kind of sucks some places.

It's pretty disturbing, not so much in the what it looks like, as it doesn't much look like an eye anymore, but just the whole thing of the police leaving behind a kid's eye as they leave the crime scene is horrifying.
